Gabor-Granger

Find the price that maximises revenue.

Gabor-Granger tests a set of price points directly against respondents, plots the demand curve, identifies the revenue-optimal price, and surfaces drop-off zones, elasticity intervals, buyer segments, and confidence intervals.

Setting a price — sound familiar?

01Guessing which price will actually sell best?
02Afraid a price hike will scare buyers away?
03Not sure how much room you have before demand drops?
04Setting one price for everyone — ignoring who pays more?

Gabor-Granger tests real prices and finds the revenue-optimal one.

01 · DEMAND CURVE

See exactly where demand peaks.

Price acceptance curve, revenue index, and soft demand.

Respondents rate each price point as "Yes definitely", "Yes probably", "Not sure", "Probably not", or "Definitely not." Gabor-Granger plots definite demand, soft demand, and the revenue index (price × demand%) together — the intersection instantly shows the revenue-optimal price.

02 · DROP-OFF ANALYSIS

Find the highest price resistance zones.

Demand drop-off ranked by severity between each interval.

Between each pair of consecutive price points, Gabor-Granger calculates the absolute percentage-point drop and the relative change. Intervals are ranked from steepest to shallowest — the steepest drop shows where raising price triggers the sharpest volume loss, your key resistance zone.

Drop-off Analysis (Price Resistance)

Demand change between consecutive price points, sorted by severity.

03 · PRICE RANGE + ELASTICITY

Three strategic price points and interval elasticity.

Conservative, recommended, and premium tiers with elasticity table.

Skari derives three actionable price recommendations from the demand curve: the conservative volume-maximising price, the revenue-optimal point, and a premium tier for higher margin. An elasticity table shows whether each interval is elastic (demand sensitive) or inelastic (pricing headroom available).

04 · PRICE SEGMENTS

Who are your price-sensitive vs premium buyers?

Respondents classified as Price Sensitive, Value Seeker, or Premium Buyer.

Each respondent's maximum willing-to-pay price determines their segment. Skari shows the share and count for Price Sensitive (lowest WTP), Value Seeker (mid-range), and Premium Buyer (highest WTP) — giving you a direct read on whether your audience supports a premium tier.

Price Sensitivity Segments

Based on each respondent's maximum willing-to-pay price.

05 · CONFIDENCE INTERVALS

Know the statistical uncertainty behind every estimate.

Wilson 95% CI for each price point demand estimate.

At small sample sizes, demand estimates carry wide uncertainty. Skari shows Wilson score 95% confidence intervals for every price point alongside definite demand, soft demand, and the revenue index — so you can see whether the optimal price finding is statistically solid or directional only.
